JOHN F. NEVVI'IALL, OF LYNN, MASSACHUSETTS, ASSIGNOR TO THE NEWI-IALLSHUTTER WORKING COMPANY, OF MAINE.

SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 445,299, dated January27, 1891.

Application filed July 18, 1890. Serial No. 359,220. (No model.)

.T all whom t may concern:

Be it known that I, JOHN F. NEWHALL, of Lynn, in the county of Essex andState of Massachusetts, have invented new and usefnl Improvements inShutterVorkers, of

which the following is a specification.

This improvement relates to a device or apparatus whereby the shutterson the outside of a building can be opened and closed ro simultaneouslyfrom the inside, being especially adapted for use in buildings which areprovided with metallic shutters intended to prevent the spread of iire,and it is an improvement on the United States Patent,

numbered 429,793, granted to me June 10,

1890, to which reference is hereby made.

In the accompanying drawings, in which similar letters of referenceindicate like parts, Figure lis an elevation representing shutters onthe outside of a building provided with my improved device or apparatus.Fig. 2 is a horizontal section taken through the shutters. Fig. 3 is avertical section taken on line or, Fig. l. Fig. #I is an enlargedcross-vertical c section of one of the boxes J below described. Fig. 5is a vertical section of the same, taken on line y, Fig. 4.

A A and A' A' represent, respectively, shutters on different stories ofa building, of which B is a wall, and D' B' windows. a d are the hingeson which said shutters swing.

The lower edges of the shutters A. and the upper edges of the shuttersA' (on the next lower story) are provided with pin's C C' or equivalentdevices, to which is pivotally secured one end of the rods or links DD', all substantially as in the said Letters Patent. The other ends ofthese connecting-rods are pivotally secured to posts E E', whoseopposite ends e e' are enlarged and perforated to receive horizontalrods I-I Il', and are rendered adj ustably rigid therewith by set-screwsf. As will be seen, all the left shutters of two adjacent stories areconnected with the rod II by means of the pins O, links D, posts E, andset-screws f, while all the right shutters are connected with the rodII' by means of the pins C', links D', posts E', and. set screws f. Therods Il H', which are parallel and placed at the same height, aresupported by rollers I I and move between them and the upper rollers I'I', all of said rollers having their bearings in the boxes or housingsJ, Figs. d and 5. These boxes are divided into two compartments by thecentral vertical partit-ion J', one compartment for each rod, and areclosed at the tops, ends, and sides, excepting only that there areperforations in the ends large enough to admit the rods, thus protectingthe rollers from rain or snow. The 6o bottoms may be open. The boxes aresupported by brackets J", secured to the outside of the building-wall Bbetween two stories.

K is a horizontal shaft extending through the wall B and having itsbearings in the 6 5 plates L and L', secured to the outer and innersides, respectively,'of the wall. The inner end of this shaft has fixedto it a bevel-gear g, which is engaged by a bevel-gear h, iixed on thevertical shaft N, having its bearings 7o in brackets N', secured to theinner side of the wall B. An arm O extends up from one of these bracketsN', and a shaft l has its bearings in said arm and in a bracket N",secured to the wall, said shaft engaging the 7 5 shaft N by means of thebevel-gear Z m, and being itself rotated by a crank q. On the squaredouter end of this shaft K is centrally fixed a lever R, to whoseopposite ends are pivotally secured the links or levers S S'. 8o Theouter ends of these levers S S connect, respectively, with the rods IIII'. It is evident, therefore, that by operating the crank q the shaftsP, N, and K are rotated and the levers R. S S' operated so as to movethe rods S5 II II' simultaneously in opposite directions, thus openingor closing all the shutters at once.

The shaft N and its connections are all in side the building, and hencenot exposed. to 9o the weather, and it may extend to as many pairs ofstories as desired. The levers R SS', which are outside the building,are simple in construction and not likely to be affected by the weather.Y

The shutters maybe locked in any p0sition by means of a latch or hook T,supported by a bracket T', said hook being adapted to Cbe dropped intoany one of the holes tin the hub q' of the lever q.

IOO

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. The herein-described improved shutterworking apparatus, comprisingthe following parts, viz: the vertical shaft N, located withinthebuilding, supported by the Wall thereof, and adapted to be operatedby a crank, the horizontal shaft K, engaged by the shaft N by means ofsuitable gear and extending through to the outside of the building, thelever R, centrally engaged by the shaft K, the substantially parallelrods H H', supported on the outside of the building between two stories,the links or levers S S, having one end pivot-ally secured to the rodsIl Il', respectively, and the other to the opposite ends of the lever R,and the adjustable parts E E and `links. D D for directly' operating theshutters, substantially as set forth.

2. In a shutter-Working apparatus, the coinbination, With theactuating-rods H H', placed horizontally outside the building, of theboxes or housings J, containing the rollers I I', said housings beingclosed at their tops, sides, and ends, with the exception ofperforations of size to admit the rods, whereby the rollers areprotected from rain or snow, substantially as described.
